OI LOGKLANI), OHIO, A. CORPORATION OF OHIO BOX FOB BEFRIGEBATED SHIPMENTS AND THE LIKE Application fled October 6, 1930. Serial 1%. 486,565.

My invention relates to. improvements in boxes made of paper machine roducts for the shi ment of fruit and ot er roduce primari y, which containers have a ody, a.

lid and an outer ridge-forming member or cuii, the purpose of which is to increase the rigidity of the container and to space the bodies of adjacent containers from each other the circulation of air. The latter fimction is of particular importance in the shipment of produce in refrigerator cars. The basic object of my invention is the provision of improvements in this type of container. More specific ob ects of 16 my invention are the provision of a new top construction and method of attaching it, together with improvements in the construction of the cufi and the attachment thereof. These andother objects of my invention sufiiciently to permit I which will be pointed out hereinafter or will skilled in the art upon reading the specification, I accomplish by that certain construction and arrangement of parts, of which I will now describe a pre- 95 ferred embodiment, reference being had to the drawing whichforms a part hereof.

In the drawing: Figure 1 is a perspective view of an open container showing one form of my cufi construction. Figure 2 is a sectional view of a side of the container of-Fi 1, showing the manner in which the lid is fitted to my box.

Figure 3 is a perspective view of a box be a parent to one Figure 4 is a sectional view of a side there of. v Figure 5 sh s the container of Fig. 3 fitted with my novel lid. l

Figure 6 shows the blank construction for the lid. 1 I Figure 7 shows the blank construction for the cufi of Figure 3. p Containers having sidewise'projections or cufis have been" disclosed in-an application of David T. Usher, Ser. No. 403,864, filed Oct. 31, 1929. In the box of this application the side members have projections which, along suitable double-score lines, are bent back upf cufi construction. p

" with the said bituminous pulp, the liner vats on themselves and are stitched to the sides to form the said projections. Such construction necessitates the use of a lid or top which fits within the sides of the box. Flaps on the cover are thus not held within the box by any direct acting force, except possibly a' frictional engagement of the said flaps between the sides of the box and the contents.

In the nature of the materials to be shipped in such boxes this pressure must be slight.

Consequently it is the practice to provide external means such as are shown in the said application hereinabove referred to for locking the cover in place. The locking means for the cover described in said Usher application may be employed with my box, although in one modification, I have provided other means for locking the cover. It is, however,

an object of my invention to provide a box and cover construction such that the box can be filled through the top thereof, and the cover can be placed in position, without inserting the flaps thereof between the fruit or other contents and the sides of the box,

.iwhether or not the box is equipped with a ray.

My box, while it may be constructed of other materials, is preferably made or com prises the 'felted product of a bituminous pulp, such as that described in the atent to Stevenson and Buron, No. 1,7 1,150, of July 22, 1930. For the sake of strength and thickness a suitable board is usually made by pasting together two or more plies of aper machine roduct; and it is preferable to make the sai plies upon a multi-cylinder machine, the central vats of which are fed being filled with a pulp of fibers, which, while they may be sized, do not contain the bituminous-binder substance. Several of-such plies may be cemented together or one of such plies may have'liner plies. of kraft or board ce-' mented to it. In the manufacture of my box, the body will usually be formed of a blank having scored portions to form the sides an attach-' men't flap which may be stitched to one of the sides, and flaps upon one end which are foldable over to form the'bottom. I have I shown in Figure 1 a box having sides 1, and.

7. The legs are brought together and the cuff is stitched to the side of the box with the base 5 near the upper edge thereof, by stitches 4, which are located toward the outer ends of the legs. Thus the body of the cuff is free from the side 1 of my box. A lid having a top portion 8 and a flap 9 may be placed on my box with the flap inserted, as shown in Figure 2, between the cuff and the side wall of the box where the said flap will be held by frictional engagement.

For greater strength as well as a somewhat simpler manufacturing operation, I prefer to make my cuffs 3 all in one piece as shown at 10 in Figure 3. To this end I provide the blank shown in Figure 7 comprising outer cuff portions 11 articulated together by scores 12 which are wider than the scores used in forming the body of the box and may be, if desired, double scores. I provide also an attachment flap l3 articulated to one of the members 12 by a score 14. Inner cuff members 15 are articulated to the members 11 by a wide ordouble score 16 and are separated by slots 17 wider than the double scores 12. In use, the blank of Figure 7 is stitched into tubular form by attaching the flap 13 to the farthest member 11, the inner members 15 are folded inwardly, and the cuff member is placed on the box as shown in Figure 3, where it is held by interspaced stitches 18 adjacent the lower ends of the members 11. In this construction the inner members 15 are shorter than the outer members so that the stitching is done through but one thickness of board in the cuff and one thickness of board-in the side wall. I prefer to use the one-piece cuff construction because it is economical of board.- In the one-piece construction, as shown 1n Figure 4, there is a space betweenthe body of the cuff and the side wall of the box into which the cover flap may be placed and frictionally held. The cover flap may also be provided, if desired, with a projection which will interlock with the inner cufi' member 15,

or I may provide a cover having the construction shown in Figure 6. Here I have articulated together by lines of scoring a lid portion 19, flap portions 20 and projections 21.

In Figure 5 I have shown one of my boxes with the stitches l8 so interspaced that the extension 21 may be passed down between adjacent stitches and between the cuff and the.

side wall as shown. As a further locking means I may provide slots 22 in the members 11 and I may score the projection 21 as shown with its folded be depressed further than the line of stitch-' ing 4' or 18 will permit the lid flaps to extend; and in that construction in which I have provided a locking method for the cover I am enabled to do away with wire hold downs or other external lock devices.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is v 1. In a container having a bottom and side walls, a separate cuff member comprising a piece of board bent upon itself and disposed portion adjacent the top edge of a side wall and stitched to said side wall by stitches passing through a lowerwedge of said cuff, said stitches interspaced to permit the passage of an extension of the cover flap between said cuff and said side wall so as to extend below said cuff.

In a container having a bottom and side walls, a separate cuff member'formed of a piece of board bent upon itself and disposed with its folded portion adjacent the top edge of a side wall, said cuff member being stitched to said side wall by interspaced stitches passing through a lower edge portion thereof and a side wall, said stitches interspaced to permit the passage of an extension of a cover flap, a cover for said container, 2. cover flap on said cover and disposed in the space be-' tween said cuff and said side wall, and an extension on said cover flap extending be-' yond said cuff in the interspace between the stitches.

3. In a container having a bottom and side walls, a separate cufl member formed of a piece of board bent upon itself and disposed with its folded portion adjacent the top edge of a side wall, said cufi' member being stitched to said side wall by interspaced stitches passing through a lower edge portion thereof and a side wall, said stitches interspaced to perm1t the passage of an extension of a cover flap, a cover for said container, a cover flap on said cover and disposed in the spacebetween said cuff and said side wall, an extension on said cover flap extending beyond said cuff in the interspace between the stitches, and a slot in the outer member of said cuff, said flap extension being bent over and inserted in said slot.

4. In a combination with a container having side walls articulated by scores, a cufl member attachment to said side walls, said cufl. member bein in one piece and comprising a plurality o outer cufi portions articulated together b scores wider than the scores between said si e 'walls, an attachment flap and a plurality of inner cufi sections separated by slots and articulated to said outer cuff sections.
